ARTHUR PULLEN-BUBRY, F SOMPTING, WO RTHING, ENG-LAND;

MOVABLE HOTHOUSE.

To all whom it may concern:

Be it known that I, ARTHUR PULLEN- BURRY, a subject of the King of GreatBritain residing at Rectory House, Sompting, lvorthing, Sussex, England,have in vented new and useful Improvements in Movable Hothouses, ofwhich the following is a specification.

This invention comprises the application of shaft and gearing to hothouses of any length and any number of spans connected in such a mannerthat the whole of the building, pipes for hot water boilers, ventilatinggear and water supply can be moved transversely, thus enabling onebuilding to suecessively cover any number of like pieces of ground.These hot houses may be glazed or not as desired. This is efiected by aframework of iron or timber upon which the roof,

hot water pipes and cold supply are fixed, the framework movestransversely upon fiat faced wheels over cement rails on a concrete bedat intervals of sixteen feet or more apart.

In order to keep the frame wheels on their pathway four or morehorizontal wheels are fixed at the corners of the framework which pressagainst the side of a steel rail mounted on a concrete bed. The ends ofthe hot houses ride upon this steel rail, and carry the first portion ofthe power producing gearing, the remainder of the power is produced by along countershaft having pinions at intervals turning the driving wheelsby a cog wheel attached to them.

The drawings illustrate a hot house made in accordance with thisinvention.

Figure 1 is a section and Fig. 2 is an end elevation, Fig. 3 is a planand Figs. 4 to 6 n show details to a larger scale.

The hot house shown consists of two spans mounted on wheels 10 and 11 atthe ends and wheels 12 within the spans. The wheels 10 and 11 run onrails 13 and 14 re- ,spectively while the other wheels 12 run onconcrete beds. At the ends also are horizontal wheels 101 and 111 whichbear against the rails 13 and 14 and guide the path of the hot house.

On the center wheels 102, 112 and 122 of the wheels above mentioned aretoothed wheels 103, 113 and 123, which are in gear with pinions 104, 114and 124 on a shaft 15 extending the length of the house, one of thewheels 123 being shown in Fig. 4. The gear wheels 104, 114, 124, arecast in one piece Specification of Letters Patent.

with sleeves 105, 115, 125, which are keyed to the shaft 15. I V

The shaft 15 is supported on the surfaces of the wheels102, 112, 122,and is heldin position by the slidin guide 16 which is in turn held byadjusta le screws 17 moving through blocks 18 cast on the frame 19. Bymeans oft-his adjustable guide any twisting of the shaft is allowed for.

The shaft 15 is turned by multiplying gear shown to a larger'scale atFig. 6. 20 is a handwheel keyed to a spindle 21 upon which is a pinion22 in gear with another pinion 23 on the spindle 24. On the spindle 24is a pinion 25 gearing with the toothed wheel 26 on the shaft 15 uponwhich are. the pinions 104, 114, 124, as above described.

The hot house is provided all around its sides with hinged boards as areshown at 27.

The boiler 28 for heating the water to be circulated in the pipes 29 isprovided with wheels to run on the rail 14. vOr alternatively to run ina trench at one end of the hothouse upon wheels upon steel rails 281.

What I claim is I i 1. A hot house, rails transverse to the hot I house,wheels upon the hot house running on the rails, a longitudinal shaftcarrying driving pinions, gearing connecting the driving pinions withthe wheels, and means for driving the shaft.

2. A hot house, rails transverse to the hot house, wheels upon the hothouse running on the rails, a longitudinal shaft carrying drivingpinions, gearing connecting the criving pinions with the wheels, andmultiplying gear for driving the shaft.

3. A hot house, rails transverse to the hot house, wheels upon the hothouse running on the rails, a longitudinal shaft turning in adjustablebearings on the hot house and carrying driving pinions, gearingconnecting the driving pinions with the wheels, and means for drivingthe shaft.

4. A hot house, rails transverse to the hot house, wheels upon the hothouse running on the rails, a longitudinal shaft turning in adjustablebearings on the hot house and carrying driving pinions, gearingconnecting the driving pinions with the wheels, and multiplying gear fordriving the shaft.

5. A hot house, rails transverse to the hot house, wheels upon the hothouse running on th rails, a longitudinal shaft carrying driving pinionsgearing with toothed wheels on the wheels, and means for driving theshaft.

6. A hot house, rails transverse to the hot house, Wheels upon the hothouse running on the rails, a longitudinal shaft carrying drivingpinions, gearing connecting the driving pinions With the Wheels, meansfor driving the shaft, and other Wheels at the ends of the hot housebearing against the sides of the rails.

7. A hot house, rails transverse to the hot house, Wheels upon the hothouse running on the rails, a longitudinal shaft turning in ad justablebearings and carrying driving pin-- ions gearing With toothed Wheels onthe wheels, multiplying gear for driving the shaft, and other Wheels atthe ends of the hot house bearing against the sides of the rails.
